Classification and Advantages of Light Weight Concrete

Sound Transmission Class Guidance - HUD

The Impact Isolation Class (IIC), measured in decibels, is the classification system used to determine sound impact from floor to ceiling in a structure. The IIC is not to be used to measure airborne sound penetration or absorption in walls. The IIC numerical rating efficiency increases with improved impact isolation performance of

14 Properties Of Aggregates And Its Importance! [Civil

When we estimate the concrete quantity, the aggregates will occupy 70 to 75% of the volume.. The classification of aggregates depends on the grain size, density, shape, and geographical origin. So the properties of aggregates will differ based on the classification, and it may influence the mix of the concrete and strength.
